Trademark Case Files Dataset

The Trademark Case Files Dataset contains detailed information on 7.4 million trademark applications filed with or registrations issued by the USPTO between January 1870 and January 2014. It is derived from the USPTO main database for administering trademarks and includes data on mark characteristics, prosecution events, ownership, classification, third-party oppositions, and renewal history.

* Note: the 2014 DTA files have been created using the Stata-13 format. Long string values are stored using the new strL variable type. Consequently, the length variables for long strings are no longer required.
